MAOBU Green Bore Sight Kit, Green Sight BoreSighter with Big Button Switch for 0.177 to 0.50 Caliber with 9 Plastic Hard Joint Adapters

It says it will fit a 177 caliber rifle barrel but it doesn't and the laser is very very weak only good in the evening time

Had one already an early modle that would not fit .177 barrels, this one does.

Good piece of kit, quite accurate for a cheap laser sighter, plenty of barrel adapters , saves time and ammo.

very useful to zero your scope especially as it is green , very visible when sun shine.

The item arrived it looked like it had been used batery was installed only lasted a week then died, the attachments were scatered in box and have no markings to help identify the correct size of caliber. a small plastic or cardboard orginizer with sizes would not be hard to do. all in all not a very well presented item.

Poorly made and no where near accurate. Dot was clearly not on centre and gave a deviation of 15" when rotated at 35 yards. Impossible to correctly align as the shaft was also not true. Different size bore attachments make it ideal for clearing various size nostrils or ear canals! Don't waste your money you will only be disappointed !!!

Good product

Tried it, and now hate it. Put in my barrel and turned it 1/4 of a turn the laser dot is in a different place every time. Don’t waste your money. Buy a rifle rest and do it properly.
